Technology Disruptions 6

Disruption: Desktop Virtualization Extreme workload consolidation necessary for economics to work More workloads on fewer drives Workload mobility Blender effect, mix of read/write ratios Impact of client OS-specific caching Impact of synchronized peaks (e.g., boot storms, login storms, virus scans) 7

Disruption: Hardware advances IOPS Latency DRAM Networking Flash Hard drive

The complexities of flash 9 Reads vs writes Write amplification Garbage collection Endurance / wear-out Consumer grade vs. Enterprise Traditional RAID / Filesystem applicability Tiering with storage system

Disruption: Hardware advances for performance Memory channel storage e.g., NVDIMM Speed comparison Non-volatile characteristics of classic flash Interface challenge for OS/Hypervisor NVMe e.g., PCI-e solid state drive replaces the AHCI stack – 1/3 CPU utilization Memory5 μsec PCI-e50 μsec SAS SSD300 μsec DRAM Networking Flash Hard drive IOPS Latency

Disruption: Hardware advances for capacity Capacity-optimized drives “Shingled Magnetic Recording” (SMR) e.g., Seagate’s 8TB SMR drive at $.03/GB (1/500 th that of flash!) Non-symmetric read/write characteristics Cloud Network speeds making it possible Can be as inexpensive as $.03/GB/month DRAM Networking Flash Hard drive IOPS Latency

Disruption: Hardware advances in networking Networking speeds continue to improve – 10GbE typical; 40GbE and 100GbE coming soon Inter-node communication clocked at 50 μsec, including TCP/IP stack More predictable speed than flash Enables scale-out storage architectures 12 DRAM Networking Flash Hard drive IOPS Latency

Disruption: Scale-out application architecture Scarcity vs. Abundance Consequences: Object storage Replicas instead of updating in place Minimized synchronization I/O performance should scale out with the application 13 Node A Node BNode C Scale-out

The storage landscape 14

Decoupled architecture All-flash arrays Hyper-converged (Software-defined) Storage in 2015 VM Hypervisor Server SSDs Controller software VM Hypervisor Server SSDs HDDs Controller VM/software HDDs Hybrid arrays VM Hypervisor Server HDDs Write log / Read cache Disk pool Controller software SSDs I/O Optimization Storage-side processing Server-side processing

All-flash arrays Storage in 2015: All-flash arrays VM Hypervisor Server SSDs Controller software “Porsche” of storage array performance Consistently high performance for all connected applications Comes at a steep price premium All drives are flash, plus the proprietary upcharge: Dell server SSD = $3K EMC storage SSD = $15K

Storage in 2015: Hybrid arrays Better price/performance calculation than all-flash Most market share is from existing vendors; the next “status quo” ? Buyer Beware: SSDs as a tier in legacy arrays vs. purpose-built hybrid array (handling of flash & architecture of write log/read cache) Hybrid arrays VM Hypervisor Server HDDs Write log / Read cache Disk pool Controller software SSDs

Hyper-converged (Software-defined) Storage in 2015: Hyper-converged VM Hypervisor Server SSDs HDDs Controller VM/software Integrated building block for an entirely new datacenter architecture Commitment to scale everything together Inefficient with storage space because of data protection schemes More appropriate for greenfield (new) deployments because of new mgmt tools and processes Typical in ROBO and SMB

Decoupled Architecture Storage in 2015: Decoupled Architecture HDDs I/O Optimization Splits storage into capacity layer and performance layer Performance layer benefits from: Hyper-locality μsec vs. msec Commodity pricing Dell Server SSD = $3K EMC Storage SSD = $15K Capacity layer can be any storage platform – keep existing tools and reporting

Infinio’s storage acceleration platform 20

Infinio’s storage acceleration platform Globally deduplicated Operationally transparent Simple to evaluate, implement, and use Software-based performance layer; optimized for RAM “We noticed the results almost instantly, with a visible reduction of storage latency on the VDI desktops and decreased workload on our filers.” --Nathan Manzi, Systems Engineer at Minara Resources

Infinio architecture 1 Accelerator VM and 8GB RAM per ESX host 1 Console VM per vCenter Communication runs over the vMotion network One solution for virtual servers and virtual desktops No changes to guest VMs “By better utilizing the existing infrastructure, I/O optimization can improve performance, and help control costs.” –Gartner Hype Cycle 2014 LAYER FOR STORAGE ACCELERATION Kernel module
